5 Protective Measures

1. Indoor antifreezing protection

When cooling in cooling mode or dry mode (that’s Tamb>Tpreset+2 ć ), if it’s detected that the evaporator tube temperature is too low the system will turn to antifreezing protection status. Meanwhile, compressor and outdoor fan will stop running, while indoor fan and swing motor will keep original status. When evaporator tube temperature resumes to normal range and compressor has stopped for

6mins, controller will run at the setting mode.

Buttons won’t be shielded during the antifreezing protection.

2. High-pressure protection of system

When the high-pressure protection is detected for 3s successively, all loads will be turned off. Meanwhile, all buttons and signal will be shielded and E1 will be displayed. When it’s detected that the high-pressure protection of compressor has been released for 6s successively, the shield for button and signal will be released and E1 will still be displayed. E1 can be cleared after pressing ON/OFF button to turn off the unit. The unit will resume running after repressing ON/OFF button.

3. Low-voltage protection of system

This function is unavailable for some modes. But if the controller is the general controller and the shielded wire of low-pressur protection is loosened or not connected well, it will take it as low-pressure protection by mistake. The details are as below:

1. After compressor is started up for 2mins, it will begin to detect the signal of low pressure switch. If it’s detected that the low pressure switch is broken for 1mins successively, the complete unit will stop running. 3mins later, if the low pressure switch is resumed, the unit will resume running automatically. If low pressure switch protection occurs for 2 times successively, E3 will be displayed and the can’t resume running automatically to warn users that it’s leaking. After restarting up the unit and low pressure switch is resumed, the unit will resume running.

25

2. When compressor is stopped, if it’s detected that the low pressure switch is broken for 30s successively, the complete unit will stop running. Meanwhile, E3 will be displayed and the unit can’t resume running automatically. Only after restarting up the unit and the low pressure switch is resumed, the unit can resume sunning.

3. When compressor hasn’t been start up after energization each time, if it’s detected that the low pressure switch is broken for 1s successively, all loads won’t be turned on after turning on the unit, and E3 will be displayed on the display screen. E3 will still be displayed after restarting up the unit. Only when the low pressure switch is resumed, E3 will be cleared and then all loads will run normally.

4. In compulsory cooling or heating mode, it will begin to detect the signal of low pressure switch after compressor has started up for

2mins. When it’s detected that the low pressure switch is broken for 1s successively, the complete unit will stop running and E3 will be displayed. During compulsory heating, if outdoor ambient temperature

̰

0 ć

, the detection for low pressure switch will be shielded.

Correct disposal method: after cutting off the power, insert the shielded wire again to make sure that the shielded wire is connected firmly and then restart up the unit.

4. High temperature protection for discharge pipe

After the compressor is started up, if it’s detected that the discharge temperature is too high for 30s successively, the unit will stop running when indoor ambient temperature is reached to setting temperature. When compressor has stopped for 3mins and discharge temperature resumes to normal range Tdischarge <90 ć

, the complete unit will resume running.

If above protection is occurred for twice successively, the complete unit can’t resume running and E4 will be displayed. When restarting up the unit and Tdischarge <90 ć , the unit will run at setting mode.

If turning on the unit to turn to heating mode or switching to heating mode from other modes, discharge protection will be shielded for

1min when compressor is started up for the first time.

5. Indoor high temperature resistance protection

In heating mode, when it’ s detected that the evaporator tube temperature is too high, outdoor fan will stop running; when evaporator tube temperature resumes to normal range, outdoor fan will be started up.

6. Overcurrent protection

After compressor is started up, if it’s detected that the current is exceeds I

0 (

I

0

=25A) for 3s successively, the unit will stop running when

Indoor ambient temperature is reached to setting temperature. After compressor has stopped for 3mins, the unit will resume original running status. If protection times exceeds 6 times, indicator will blink and display E5 and the unit can’ t resume original running status.

The unit can only resume running after restarting up the unit.

7. Malfunction of temperature sensor

Under ON status, it will detect the malfunction of indoor tube temperature (exclude defrosting period and the period when defrosting is finished for 5mins) and outdoor discharge temperature sensor (in heating mode, it starts detecting the malfunction after compressor has started up for 1min; the malfunction won’ t be detected when compressor is stopped). It ’ s the malfunction when they are short circuit or broken circuit for 30s successively. When there’ s malfunction of temperature sensor, the complete unit will stop running. Meanwhile the indicator will blink and display the corresponding error code. Malfunction of temperature sensor won’ t shield the button and remote controller.
